The altitude of point A (top point of hemispherical cup) : relative to B.
= radius = 25 cm
PE = m g h = 0.250 kg * 10 m/sec^2 * 0.25m = 0.625 J
speed at B: v m/s
KE at B = PE at A --- energy conservation.
1/2 m v^2 = 0.625 J
v = 5 √2 m/s
It is not clear where the point D is ....
If we know the height at point D, then we can calculate PE and then find the KE by 0.625 J - PE.
